lb alt whom "it may cofrwcm:` I

zen of the United States; residing in lMer# :cbantvil-le, county of Camden, State of New i, Jersey,- .have invented a new and useful Utensil-Sterilizergg'of which the following is `:l

' y F ig. -5 represents aside elevation, partly 1n a specification.' f My invention conslstsiof a' novelconstruc` tion of utensil sterilizer, wherein provlslon 1s .150 made for supplying a suitable tank with Water or other liquid'and then withdrawing the saine, means being' also provided for heating said water yor `liquid tothe desired i lextent and provision being also made for raised into an accessible position bythe raisv ing of a cover actuated by foot power, where-- 25- treadle and connections therefrom to said lid.

My invention further consists of a novel vconstructionof dash potconnected saidi lid, whereby the descent of the lid isautomatically retarded Without requiring attenso f tion on the part of the operator.

` To the abovev ends my lnvention consists Yof a 'novel construction of utensil sterilizer,l

wherein novel means are provided lfor .heat-- ing the sterilizing tank7 for raising and ylowering the receptacleforthe articles to be steril? i ized simultaneously with the' lidandA for;y

further permitting the.; descent'of the. lid" to be automatically retarded' allof which is etfected by afoot operated treadle,'thus leav-j vlate'the articlesto be sterilized. For .the purpose of illustrating my `inven v tion I have shown in the accompanying draw# .ings one forn' thereof which is iat present preferred by .me',` 7since the lsame has been found in practice to give satisfactory and reliable results, althoughit is to be under-4 'stood that the 4various instrumentalit-ies of which my invention 'consists can be vari invention isynotvlimited to the precise arrangementjand organization of thes'einst'ruimentalities as herein shown and described.

In a similar manner the chain 36 passes around the pulley 40 and thence over the pulley 41 and has its extremity 42 hooked or otherwise secured to the cage or basket 43, it being noted', as will be understood from Fig. l, thatthere are two sets of chains and pulleys arranged o ne at eachslidekof the sterilizerl'tank s'o that tie cage or as et 43 is 1:0 er .-su orted in its substantially horizontal pt )ysitioipwhen at rest in its lower ppsition, as seen'inFigs.' 1 and 2 or Wheniaised to its elevated posi-y tion seen in Fig. 3. The pulleys 41, 40, 37- and 38 I nay be nounted in bearings secured to the upper interior opposite sides of `the tank 2 in any convenient manner and in the present instance I have shown a preferred form of assembling and mountingsaid pulleys, consisting of a bar 44 which is adapted to be riveted or otherwise secured to the op@ posite inner walls of the tank2, said bar being provided with'the Vstrip or plate 45 secured thereto, as will be understood from Figs. 5 and`6, wherefrom it will be apparent that the pulleys can be readily assembled upon -their bearings and the bar or plate 44 carrying the saine can then be readily riveted or secured to the opposite upper inner walls of the tank, as indicated in Fig. -1, in

the desired position. A

shown my inventionas especially adapted to have/the contents of the .tank heated by steam or other fluid which entersthrough .the pipe 11 and which is discharged into ing the sterili'zing tank' exteriorlythrough the medium of 'a' hydro-carbon burnerfs'uch lfor example as'is lshown -in Figs:A 8,'9l yand 10, wherein 53 designates .the""bu'ner tube,

into which the hydro-carbon is conducted through the inlet pipe 55, whichis "provided with a valve 56, the device 57 beingprovided .with ports 58 `Wherebya siiilicient quantity of atmospheric air isperi'nitted to' enter for the purpose of assisting the combustion of the hydro-carbon. 'The detailed construction of such burners will be familiarto those skilled in -the art 'andI have deemed it unnecessary todescribe the same in further detail. l.

The operation is as lollowsz-The'parts normally appear as seen in Figs: land'2, wherein the lid or co'ver'16'is shown as-being closed,' the cage or baskety 43 is in .its lower position and --the vtreadle 28 and' its adj uncts .is shown`in its elevatedor inopera tive position. Whenit is desired to sterilize the utensil or other articles, thel tank 2 is is permitted to enter through` the pipe 7,

After the tank is filledv with position seen in. Fig. 3. Thethe position seen inFig. .3, .wheneupbn the it win be ,apparent thatv what. i have irst'filled or partially so with water-which onlynecessary for the operator to depress .l

and 2 andthe sterilizing operation can bev by theoperator, since his hands are free for l thisv purpose.

.In order to close` the sterilizer it is only necessary to disengage the treadle or lever 28 from the stop or shoulder 33, whereupon the parts assume the position seen in Figs. 1

continued to the vdesired extent. Through the medium of the dash potcylinder 46 the piston'l, the rod 49 and their adjuncts, it

will be evident that the descent` of the ro'd,

sterilizer whose cover can be opened by foot power and automatically closed lwithout requiring manual attention from the operator `and the sterilizing receptacleis also auto'- matieally raised simultaneouslylwith the ele.-y

vation ofthe cover. v

It will be apparent that the opening and closing of the sterilizer is effected'with'out requirlng manipulation on' 'the part of the operator, thus leaving his hands. free to remove and manipulate the vutensilsto .be stel'-l ilized.y

It will bie-'apparent that v.slight changes' may be made by those skilled in the artl in the manner of supporting'th'e vsterilizing:

cage or basket 43 and in the mannerof heating the tank and effecting the raising. and

lowering of the sterilizing lid and .the operation of the d ash pot, which will come within' thescope of. my invention .and Il therefore reserve to myself the right-to make all such changes that come Within the spirit of the 'same anddo not'desire to be limited in every instance to the exact4 construction I have herein shown and described.
